WEIGHT-CORD AND ATTACHMENT FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 326,392, datedSeptember 15, 1885.

Application filed May 20, 1885. (Model.)

To all whom it may concern.-

Be it known that I, EDWARD T. BRADBURY, of Mahanoy City, in the countyof Schuylkill and State of Pennsylvania, have invented new and usefulImprovements in Weight- Cords and Attachments for Windows, of which thefollowing is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional elevation of a part of a window sash and frame,showing the ap-- plication of my invention; and Fig. 2 shows the cordand its attachments.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

The cord a has the metal block I) attachedto one end, and thescrew-clamp G and hook d attached to the other. The hook d is forholding weight 6, that moves up and down in the channel f, made inwindow frame A. as the Window B is raised and lowered. The cord or, whenapplied for use, passes over pulley g in the ordinary way. The block bis for attaching cord a to the window B, and is a plain block of metalformed with passage h to receive the end of the cord, and with thethumb-screw i for securing the cord; and for making the attachment ofthe block to the cord more secure I form an opening, j, in the blockopposite the screw-threaded opening 2', that receives the screw 2', sothat when the screw is turned down upon the cord a portion of the cordwill be pressed into the openingj, thus preventing any slipping of thecord.

The clamp O is made with two parts or sections, a o, and a nut orsleeve, is. The sections 0 c are screw-threaded upon their outersurfaces, and correspondingly recessed at their adjacent surfaces, asshown at 0 to form a circular cavity for the end of the cord (1. Uponthe parts or sections of the clamp O is screwed the internallyscrew-threaded nut or sleeve k, which serves to press the parts 0 0together to cause them to grasp the cord a. The nut or sleeve isshouldered at-k, to hold the hook d, which is formed with ring (1 toencircle the clamp O and rest upon the shoulder is, as shown clearly inthe drawings. The parts 0 o are knuckled togetherthat is,

the part c is recessed at c and the part c is formed with anenlargement, c, to fit in recess c to form a rocking center or fulcrumon which the parts 0 0 open and close. With this construction, when thenut or sleeve is is screwed below the enlargement and recess 0 c, theupper ends of the parts 0 0' may be opened to insert or remove the endof the cord a without entirely removing the nut or sleeve. The end ofthe cord being inserted,

- it is only necessary to screw the nut upward upon the sections a 0,which will close them upon the cord and cause them to grasp it as ,in avise.

To prevent all danger of the cord slipping between the sections 0 c, Iform them with the ribs or teeth 0 in the cavities c", which teeth willbe embedded in the rope when the sections are pressed upon it, as willbe understood from Fig. 2.

The block bis of a size to be inclosed by the. cavity Z, made in theedge of the sash B below the shoulder m, so that it will not interferewith the up-and-down movement of the sash. With this block, in case thecord a requires to be shortened, the stop-bead has simply to be removedfrom the windowframe, the window swung out at the top, the thumb-screw tloosened, and the cord drawn through the block and the screw tightenedupon it again, all of which can be quickly and easily done.

The clamp C may be very easily and quickvent the raising or lowering ofthe window.

Having thus described my invention, what,

I claim as new, and desire to secure by Letters Patent, is

- l. The screw-threaded sections 0 c, in combination with thescrew-threaded sleevek and hook d, the sections 0 0 being formed withshoulder k and the hook with ring d, substantially as described.

2. The externally screwihreaded sections 0 a, recessed, as shown at c,and formed, respectively, with the recess 0 and enlargement 0, incombination with the screwthreaded nut or sleeve is, substantially asand for the purposes set forth.
